1.字段过长截取字符串

1.1 截取字符串类

 

可以直接substring
也可以<%# Utility.Common.GetShow( Eval("NewTitle").ToString(),20,true) %>
    <td><%#fcwms.Common.GetContent.GetShow(Eval("com_address").ToString(), 19, true)%> </td>


        /// <summary >
        /// 按字节数截取字符串,中文算两个字节,全角字符算两个字节,大写字母也算两个字节
        /// </summary >
        /// <param name="strSrc">要处理的字符串</param>
        /// <param name="count">要保留的字节数</param>
        /// <param name="withPoint">设置截取后加不加省略号( "... ")默认的传true</param>
        /// <returns></returns>
        public static string GetStrByByteCount(string strSrc, int count, bool withPoint)
        {
            Regex regex = new Regex("[\u4e00-\u9fa5]+", RegexOptions.Compiled);
            char[] stringChar = strSrc.ToCharArray();
            StringBuilder sb = new StringBuilder();

            for (int i = 0; i < stringChar.Length; i++)
            {
                if ((regex.IsMatch((stringChar[i]).ToString())) || (stringChar[i] > 65280 && stringChar[i] < 65375) || (stringChar[i] > 64 && stringChar[i] < 91))
                {
                    nLength += 2;
                    if (nLength > count)
                    {
                        isCut = true;
                        break;
                    }
                    sb.Append(stringChar[i]);
                }

                    {
                        isCut = true;
                        break;
                    }
                    sb.Append(stringChar[i]);
                }

            }
            if (isCut)
            {
                if (withPoint)
                {

                }
                else
                {
                    return sb.ToString();
                }
            }
            else

1.2 示例

 <td><asp:Label ID="Label14" runat="server" Text='<%# fcwms.Common.GetContent.GetShow(Eval("com_address").ToString(),19,true)%>'  ToolTip='<%# Eval("com_address")%>'></asp:Label></td>

 

<td><asp:Label ID="lblMatNM" runat="server" Text='<%#Eval("matNM").ToString().Length >10?Eval ("matNM").ToString().Substring (0,10)+"...":Eval ("matNM").ToString ()%>' ToolTip ='<%#Eval("matNM")%>'></asp:Label></td>

无提示：

 <td><%#fcwms.Common.GetContent.GetShow(Eval("com_address").ToString(),19,true)%></td> 

2.时间格式化

<%# Convert.ToDateTime(Eval("time")).ToString("yyyy-MM-dd HH:mm")%> 

<%#string.Format("{0:yyyy-MM-dd HH:mm}", Eval("time"))%>

<%#string.Format("{0:g}",Eval("add_time"))%>   2018/4/2 15:03

3.合并单元格

 <td runat="server" id="tdName"><%#Eval("td_name")%></td> 

rptList.DataSource = pds;
        rptList.DataBind();
　　　　　//合并方法放到数据邦定之后
        for (int i = rptList.Items.Count - 1; i > 0; i--)
        {
            HtmlTableCell oCell_Previous = rptList.Items[i - 1].FindControl("tdName") as HtmlTableCell;
            HtmlTableCell oCell = rptList.Items[i].FindControl("tdName") as HtmlTableCell;

            oCell.RowSpan = (oCell.RowSpan == -1) ? 1 : oCell.RowSpan;
            oCell_Previous.RowSpan = (oCell_Previous.RowSpan == -1) ? 1 : oCell_Previous.RowSpan;

            if (oCell.InnerText == oCell_Previous.InnerText)
            {
                oCell.Visible = false;
                oCell_Previous.RowSpan += oCell.RowSpan;
            }
        }
